Benefits of technology

The present invention relates to an electric power tool with a battery pack that matches the size of the tool for easy handling. The battery pack is positioned in the tool's housing to minimize the risk of blockage during cutting action. The battery pack is also positioned in a way that maximizes the use of space and reduces the risk of damage to the tool. These features make the tool easier to operate and more efficient.

Problems solved by technology

Such a battery pack has usually a parallelepipedal shape and is received partially in the battery pack compartment so that the device housing of the power tool is of a bulky shape because of the externally attached or only partially inserted battery pack; therefore, handling of the power tool is made difficult.

Embodiment Construction

[0022]The battery pack 1 illustrated in FIG. 1 is comprised of a cup-shaped battery pack housing 2 that is closed off by a cover 33. The battery pack 1 serves as an energy source for an electric power tool, in particular for a hand-guided power tool such as a motor chain saw, a hedge trimmer, a cut-off machine, a brush or grass trimmer, an edger, a pole pruner, a blower, a sprayer, a vacuuming device, an earth auger, a multi-task power tool for multi-functional attachments, a sweeper, a rotary hoe, a rototiller (cultivator), a high-pressure cleaning device, a lawnmower, a dethatcher, a chopper or shredder, a wet / dry vacuuming device, or a similar power tool that is preferably portable. The illustrated battery pack 1 has an approximately parallelepipedal basic shape that extends in the orthogonal spatial directions x, y, and z. Thus, the battery pack 1 has a height axis H, a width axis B, and a depth axis T. The height 10 in the direction of the height axis H is embodied such that it...

Abstract

An electric power tool has a device housing with a rear grip extending in the longitudinal direction of the device housing. The device housing has first opposed housing sides and second opposed housing sides. An electric drive motor and its electronic control are arranged in the device housing. A battery pack compartment arranged in the device housing receives a battery pack that has a parallelepipedal shape and extends in a direction of a height axis, width axis and depth axis. The battery pack is arranged such that the width axis and the height axis extend transversely to the longitudinal axis of the device housing. The battery pack has narrow sides extending approximately parallel and at a minimal spacing relative to the first opposed housing sides, respectively. The battery pack has opposed end faces neighboring the second housing sides, respectively.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to an electric power tool, in particular a portable, hand-guided power tool such as a hedge trimmer, a motor chainsaw or the like, comprising a device housing that has a rear grip extending in the direction of the longitudinal axis of the device housing as well as a housing bottom and housing sides, wherein in the device housing an electric drive motor as well as an electronic control for operating the drive motor are received. The power tool has a battery pack compartment arranged in the device housing for receiving a battery pack, wherein the battery pack has an approximately parallelepipedal shape. The battery pack housing extends in all three orthogonal spatial directions in the direction of a height axis, a width axis and a depth axis.[0002]Such electric power tools are known. In the device housing of the electric power tool a battery pack compartment is provided for receiving a battery pack. Such a battery pack has usually...
